Backflow Testing in Woodinville, WA
State-certified backflow testing, repair and installation for Woodinville homes, HOAs and businesses, with your test report filed with your water purveyor for you.
- WA-certified testers
- Reports filed for you
- 24/7 emergency dispatch
Woodinville's wine country, farms and acreage properties bring cross-connection hazards you don't see in a typical subdivision: winery and tasting-room process water, agricultural irrigation, livestock watering and chemical injection systems. Most of these call for reduced-pressure assemblies, and we test, repair and install them all.
We also serve the homes in Wellington, Leota and the Hollywood Hill area, where irrigation assemblies are the most common thing we test.

Who is your water purveyor in Woodinville?
Your purveyor is the water utility that sends your annual test notice and receives your test report. Depending on your address, Woodinville properties are commonly served by Woodinville Water District.
Not sure which one is yours? Check the top of your water bill or the test notice itself. Or just give us your address when you book and we'll figure it out and send your report to the right place.
Local know-how
Wineries, breweries and distilleries use cleaning and processing chemicals that make them high-hazard connections. We can survey a facility, recommend protection for each process line and keep every assembly on an annual testing schedule.

Woodinville backflow FAQs
Does my winery need a reduced pressure backflow assembly?
Almost always. Wineries, breweries and other beverage producers use chemicals for cleaning and processing, which purveyors classify as a high health hazard. That typically means a reduced pressure backflow assembly at the service connection or on specific process lines. We can survey your site and recommend the right protection.
Do you serve rural properties outside Woodinville city limits?
Yes, including Cottage Lake, Hollywood Hill and the surrounding unincorporated areas, as long as your property is on a public water system that requires testing.
